ORE-CONCENTRATOR.

Specification of etters Patent.

Patented Nov. 25, 1919.

Application filed November 13, 1915. Serial No. 61,274.

To all whom it may concern:

Be it known that I, GEORGE T. CooLEY, citizen of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Ore Concentrators, of which the following is a specification.

My invention relates to an improvement in ore concentrators and the present invention is intended to do its work under water.

The object is to provide a machine which is adapted for the concentration of all kinds of ores, my intention being to not only provide a machine of universal application but also one which will practically efiect a 100% saving of values.

This I accomplish in the main through the instrumentality of three motions, to wit a jig motion, atable motion and a pan motion, and especially constructed rifiles, the ore working down the inclined sides of and lodging in the bottoms of the rifiies, due to stratification, whence it is carried forward through the machine and drawn off through the valves for that purpose The accomplishment of these objects is obtained through a number of mechanical instrumentalities which combine and cooperate with one another and which will behercinafter fully described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a view in perspective;

Fig. 2 is a vertical longitudinal section, the center of the machine being broken out;

Fig. 3 is a view in perspective of the crow foot toggle, enlarged;

Fig. 4 is a sectional view of the elevator;

Fig. 5 is a vertical transverse section;

Fig. 6' is a view in perspective of a portion of the operating mechanism; 7

A. represents the main frame of the machine and B is'the concentrator. The bottom of the concentrator is in the form of inclines 1 and riflies 2 which extend throughout the length of the concentrator and to which the inclines lead. I

The'concentrator is supported atone end upon the crow foot toggle 3, the tenon 4 of which enters themortise 5 of the plate 6 in the rocking of the toggle, and the toes 7 of which strike the plate abruptly at either end of the mortise causing the table to rise and t'all'with more or less jar at the end supported by the crow foot toggles.

The other end is supported on a many sided roller 8. This roller preferably has 16 faces and the trunnions 9 at its ends are journaled in notches 10 in the cage 11 and the elevation of the concentrator B is regulated by adjusting this roller in notches higher or lower down in the cage, and the reciprocating movement which is imparted to the concentrator causes a trembling action to the table at the discharge end which is necessary in order to settle all kinds of ores which are heavier than their gangues.

A wedge block 12 on the inner face of the post 13 has an inclining outer edge which engages a similar wedge 14 on the table which latter imparts side or lateral motion to the table as it reciprocates, thus providing the pan motion so essential in the concentration of most ores.

At the feed end of the table the screen 15 is placed and into this the material to be operated upon is delivered. The over size passes over the screen and drops out and the material that passes through the screen falls down the incline 16 into thc'bottom of the concentrator table or bed B, through which it is swept by the scrapers 17 carried by sprocket chains 18 over sprocket wheels 19 and 20.

A bafilc board 21 at the discharge end is adjustable and adapted to be placed about 6 inches from the bottom of the concentrator B, its function being to cause the ore to pass beneath, thus preventing any from floating to the surface. An elevator 22 revolves at the discharge end and sweeps out the tail.- ings which are discharged at the outlet 23 while the values continue on beneath the shield or plate 24 to the ends of the rifiles 2, discharging finally through the valves 25.

The elevator is of very simple construction and may be made of a 6 by 6 block of wood with strips nailed thereto as shown in detail in Fig. 1- and while its dimensions "may, of course, be varied, it is preferably about 30 inches in diameter in a full sized machine, and it effectually sweeps the discharge end of the concentrator which is curved in the arc in which the elevator turns so that the wings of the elevator sweep the late the latter, power being applied to the drive shaf through the wheel 29.

A sprocket chain extends over a sprocket wheel 81 on drive shaft 26 from which point it passes a sprocket wheel 32 on the shaft 33 and the drag line chains 18 pass over wheels 31; and 35 carried on this shaft 33 and also over wheels 36 and 37 carried by shaft 38, and the chain 39 extends over a sprocket wheel 10 on the end of shaft 33, over a sprocket wheel. 4-1 on shaft 42 and around sprocket wheel 48 on shaft 38, and a sprocket chain 4,4 extends over a sprocket wheel 45 on the opposite end of shaft 42 from wheel 4C1 to a sprocket wheel 46 on the shaft which drives the elevator.

The machine is so geared that the drag lines including thescrapc cross the machine five times per minute; the gangues do not have to be washedand there is no end to the capacity. The elevator oscillates with the machine and consequently when on dead center the elevator wheel 29, is in line with. the drive shaft 42 above so it only plays on both sidesv of the center about one inch whiclrdoes not makeany material difference in the sprocket chain. The scrapers by traveling across the machine to the tail endkeep all materialloose at the bottom, at all times so that the stratification can easily take place, thus avoiding the danger of its becoming packed and leathery, which retards concentration.

The machine has from 1,4; to a 3 inch stroke, this depending on the ore being treated as well as the capacity at the last 1; inch of the stroke, and the wedge blocks 12 and 141- impart a side swing to the machine at the discharge or tail end which is very elfective and keeps the ore from packing the valves.

The roller 8 is set in a higher or lower notch 10 in accordance with the ore being treated. For instance, when a thin ore is being treated the roller is set in a lower notch giving the concentrator more fall or slip making the bed steeper and causing the material to travel faster and in this way it has greater capacity.

It is doubtless understood that water is not used as in a or an ordinary concentrator table, for the water in this machine does not flow off of the machine. It simply requires enough water to keep the ore saturated which is not over one-fifth as much water to handle a ton of ore as, in a jig or concentrator table.

The crow foot toggle causes the front end of the bed to pump up and down approximately of an inch while it glides about 2 inches and the fiat-faced roller 8 gives the bed about 4 inch up and down motion at the tail end with the same glide that the head end has, whereas the wedge blocks 19, and 1.4 give it a :side or lateral motion of say 9 inch and with these three motions comblned it IS imposs ble for ore to escape setthng and the drag lines dellver the tailings to the elevator wheel and out, the ore slipping from the apeXes on the bottom down the inclines 1 into the riflies 2, aided by tne motion of the crow foot toggles, and after lodging inthe riffles the concentrates travel to the discharge end under the shield 2e and out through the valves 25.

The crow foot toggle also imparts a jarring motion to the screen which keeps the material fed into it from binding and clogging.

Obviously the ize and capacity of the machine may be indefinitely varied and I propose to make it from 3 to 8 feet wide and about 10 feet in length and with the fulcrum provided by the crow foot toggle the machine is rendered very easy and light to operate.

I claim:

1. The combination with a main frame, a concentrator the bottom of which concentrator is in the form of transverse inclines, riitles which extend longitudinally of the concentrator, means for constantly reciprocating the concentrator and means for jarring the concentrator upwardly as it reciprocates, of scrapers which sweep over the riflies from the feed toward the discharge end of the concentrator, endless chains to which the scrapers are attached, and means for carrying and for driving said'chains.

2. The combination with a main frame and a longitudinally rifliedconcentrator, of means for reciprocating the concentrator lengthwise the rifiies, traveling scrapers which constantly sweep the rifles from one end to the other, and means at each end of the concentrator for imparting a trembling or jarring motion thereto as the concentrator reciprocates,

3. The combination with a main frame and a longitudinally rifiled concentrator, of means for reciprocating the concentrator lengthwise the riiiles, traveling scrapers which constantly sweep the riflles from one end to the other, and three independent means which impart unitedly an upward and downward movement to the opposite ends of the concentrator and a lateral motion thereto.

' l. The combination with a main frame and a riflied concentrator, of means for re ciprocating the table lengthwise of the ritlies, means at each end of the table for imparting a trembling or airmg up and down motion thereto, and-means at one end for imparting a lateral jarring motion to the table as it is reciproc'ated lengthwise.

The combination with a mainframe and a concentrator, the bottom of which is in the form of inclines and rifiles extending lengthwise thereof, 10f" means for reciprocating the table lengthwise of the riflies, means at each end of the table for imparting a trembling or jarring up and down motion thereto, the means for imparting a trembling motion at one end comprising a crow-foot toggle pivoted or hinged to the concentrator and the frame provided with a mortise to receive said crow-foot toggle whereby to cause the concentrator to be alternately jarred u and down with the vibrations of 10 the togg e due to the endwise reciprocation of the concentrator, and scrapers for constantly sweeping the rifiles lengthwise.

In testimony whereof I aflix my signature. GEORGE THOMPSON COOLEY. Witnesses:
